IMPROVEMENT IN MACHINES FOR CLEANING MACHINE-CARDS.

Specication forming part of Letters Pa'tent No. 27,495, dated March 13, 1860.

To @ZZ `whom it may concern:

Be it known that I, HORACE WooDMAN, of Biddeford, in the county of York and State of Maine, have invented a new and useful @aiding-Machines; and l hereby declare that the following specflcation, in connection with the accompanying drawings and references marked thereon, constitute a lucid, clear, and exact description of the construction and use of the same, in referring to the said drawings.

Figure l denotes a plan or top View of a carding-machine with my invention applied thereto; Fig. 2, a side elevation; Fig. 3, an

elevation ofthe same. 4 The nature of my invention has for its'object great simplicity, durability, and strength for constantly performing the functions necessary; and it consists, first, in raising, snspending, cleansing, and replacing the top flat carding-machine and between the arches and ends of the main cylinder, and the brush-bar placed and operated between these incline planes and over the card-cylinder; second, in the secondary incline planes so connected to the main inclined planes as to elevate themselves, and they in turn elevate the top flat cards when these planes pass from the feedplanes depress themselves and the top flat bring the cards and brush-bar together for cleansing it after it has cleansed the cards; third, in imparting an intermittent motion to the brush-bar by -the arrangement of the notched wheel, pawl, and cam or guide; fourth, in imparting to the incline planes andV movement, to first cleanse all the top fiat cards and then one or more and then back and cleanse all again, and so on, to give an increased cleansing to the top iiat cards mostneeding it; fifth, in giving the total and partial movement of the incline planes and bined with pawl, Wheel, and cam; sixth, in so comb that the llatter will cleanse the former;

at each cleansing it gives the top iiat cards.

'lo enable persons skilled in 'the art to which my invention appertains to construct and carry out the sa1n'e,l will describe it, as follows.

All necessary portions of the ordinary carding-machine are shown for the application of my invention, viz: A denotes the frame; B, the arches; C, the top flat cards having card lleting or clothing attached to their under parts in the usual manner. a denotes the pins for guiding and retaining the top flat cards in place; D, the central or main cylinder-shaft, the cylinder not being shown; E, the journal-boxes, in which the shaft D is suspended so as to freely revolve. The other well-known portions of the carding-machine arel not shown, they not being necessary in describing my invention. These several parts are Well known and in common use, and do not, when taken separately, form any part of my invention.

The projecting ends of the journal-boxes E are turned so as to receive the arms G, which freclytnrn or swing thereon, and are held in place by rings l-I and setscrews c'. These arms Gr are bent inward', as seenat I, and pass up between the arches B and the ends of main card-cylinder, (not shown,) and terminate in a double-edged incline plane J, While the lower ends of the inclined edges being regular or irregular, may be moved' from the same center as the card-cylinder or otherwise. Each of the arms G extend below the center of boxes E, to receive one end of each of the connecting-rods K-for its movement and operation, as will be hereinafter seen.

Between the upper ends of arms G or incline planes J there is fixed firmly a brushbar, (seen at L, Fig. 1,) the top flats C being broken out to show it, the top of which is snpplied with a strip of card iilleting or clothing.

The incline planes seen at J are so constructed and so operate in conjunction with the top tlat cards by coming in contact With their edges (seen at e) and first raising them by inclines c, and then suspending them on the flat or top portion of these incline planes J, while the brush-bar L and its .card comes or passes in effectual contact with the'cardteeth on the under side of. the top iiat cards which are raised, and thus cleanse them,and

arms G are passing toward the feeding end to4 be cleansed, in order that no contaotof cards and brush-bar may take place in this movement. To effect this, I construct two secondary incline planes. (Seen at M.) In each of these are formed two slots r, a portion of each being at right angles with arm G and the other part at an angle of about forty-five degrees with the first part, and through the slots o' are placed pills s, which are secured to main incline planes J on arms G. These pins s constitute the stop-motion to planes M, up and down or back and forth, by striking each end of slots fr for that purpose when the planes M are moved either Way by the reversal movement of main incline planes J, and are also to allow of the desired and free movements of these secondary inclines M on the main inclines J, and still retain and stop them thereon.

If the arms G and brush-bar L be moved from the feed end of the carding-machine, the edges h of the top lat cards C come in contact with the ends t of secondary double incline planes M, and thus move and raise them (the incline planes M) by the slots r fol* lowing the pins s' until the level portion of slots r arrives on these pins s. By this movement the incline planes J- are virtually extended upward, as seen at Figs. 2 and 3, so as to effectually lift the top flat cards higher during this movement than in the opposite movement. For cleansing the cards in that case or in the forward movement for cleansing the top liat cards their edges or sides e come in contact with ends zu of secondary i11- cline planes M and push them along and down7 they being guided and stopped by means of their slots r and pins s, so that their top and inclined edges shall be as low as the top of the main inclines J.

A shaft (seen at N) is suspended so as to freely revolve in journal-boxes O, Fig. 4. This shaft may represent the feed-roll shaft, and receive its movements by belt and gear from any movable portion of the carding-machine.

-To one end of the feed-roll shaftN is secured a balance-wheel A2 and handle B" and to the other end a crank P, which is connected to comb-crank Q by rod R. The comb-shaft is seen at S suspended by stands C2, and the comb at T connected to shaft S by arms Y,

' which is for the purpose of lcleansing the card on brush-bar L, Fig. l, by effectual contact with, it, and depositing the cotton or Waste in trough or screen U, the brush-bar L passing to and remaining near this comb'l, to allow it to be so cleansed thereby.

Near the end of shaft N is fixed a pinion V, which meshes into and drives stud-gear W, its stud being seen at D4, Fig. 2, and this gear in turn meshesinto and drives stud-gear X, turning on stud D2, and which drives gear Y, placed so as to tu rn bot-h with and on shaft Z, and this shaft is suspended to revolve in journal-boxes A2, and has a crank 2 fixed to each of its ends,which are connected to each lower er d of each of the arms G by rods K, and by which motion is given the arms G; and it is desired to impart alternate motion and rest to these arms G, and consequently to the brush-bar L, and still allow the gear Y to continue its turning or revolutions. To effect this, I place and secure a blank Wheel D2 on shaft Z, near to the gear Y. The Wheel D2 has two notches, one cut in each opposite side of its periphery, (seen at on) and into which a pawl E2, connected so as to turn on gear Y, forced down by spring F2, and secured to gear Y, and is thereby caused to engage with wheel D2 when revolving, and so continue until the brush-bar L, Fig. 1, moves to the front end of the carding-machine. Then the pawl E2 is disengaged from wheel D2 by `coming in contact with the edge of fixed guide G2. At the moment the pin or stud H2 comes in contact with end of arm l2 and reverses the movement of brush-bar L, (and intervening parts,) so that the brush-bar L will travel forward under one, two, or more of the top flat cards until the pin or stud H2 passes the end of arm I2, after which the pawl E2 will again engage with wheel D2 and put the shaft Z and brush-bar L into motion to move back to the rear end of the carding-machine, ready to again cleanse the top fiat cards by movement and effectual contact of card-teeth on brush-bar L with those on the .under side of the top flat cards, and so on ad zngnitum.

The pin l-l2 may be adjustable in gear W, so as to be moved to or from the center, which will cause a greater or less movement of arm l2, and consequently give the double cleansing to any desired number of the top flat cards, as a part of them take the greater part of the Waste from the cotton.

Thediierent figures of the drawings 'indicate four several prominent'and different positions my invention assumes, in order to better illustrate its operation-e. g., Fig. l shows the brush-bar L at the extreme front movement and all other parts of my invention in corresponding position. Fig. 2 denotes the incline planes J and M, raising the central and highest top flat cards in passing from the front to the back end of the machine, the planes M being in position on planes J to raise the top ilat cards so high as not to allow the teeth to touch with the teeth of the brush-bar L, and all other parts in corresponding position. Fig. 3 represents the incline planes J and brush-bar L at their eX- treme back end position ready to commence cleansing the cards by its reverse or forward movement., and all other parts in corresponding position. Fig. 4L represents the brush-bar L and the incline planes J at the time the eX- treme forward position is had for the reversal or double movement of brush-bar L under the first two or three top flat. cards for giving them a double cleansing, and represents all other parts in a corresponding position.

Various modifications may be made of my within-described invention Without changing or avoiding the principle contained therein; but I have shown What l deem the most effectual mode of carrying it out for the purpose specied.

Having thus described my invention, l will state my claim as follows:

l. Raising, suspending, cleansing, and replacing' the top flat cards by incline planes J, moved Within the carding-machine and between the arches and the end of the main cylinder, and the brush-bar L, placed, secu red to,

and operated by and between these incline planes an d over the card-cylinder, essentially in the manner and for the purposes fully set forth.

2. The secondary incline planes M, so constrncted and connected to the main incline planes J as to elevate themselves by contact with top flat cards, and they in turn elevate the top flat cards when these incline planes M pass from the feed-roll toward the doffer, and they being depressed by contact With,

and also the top Iiat cards with them, in the return movement and bring the card-teeth of the cardsrand brush-bar etfectually together for cleansing the cards, essentially in the manner and for the purposes fully set forth.

3. imparting an intermittent motion to the brush-bar L by the combination and arrangement of the notched Wheel D2, pawl E2, and cam G2, in the manner set forth.

4. Imparting to the incline planes J and M a complete and then a partial movement to first cleanse all the top fiat cards once, and then one or more the second time, and then back again to give an increased or double cleansing to the top fiat cards most needing` it, essentially in the manner and for the purposes fully set forth.

5. Imparting first a complete and then a partial movement to the brush-bar L by means of the stud H2 and arm l2, combined with pawl E2, cam or guides G2, and wheel D2, or any equivalent combination, essentially in the manner set forth.

6. So arranging and operating the brushbar L, in connection with comb T, that the latter will cleanse the former at each cleansing itgives the top flat cards, essentially in the manner and for the purposes fully set forth.
